Texas Instruments MSP430F261x / MSP430F241x Mixed-Signal MCUs

Texas Instruments MSP430F261x / MSP430F241x Mixed-Signal Microcontrollers (MCUs) are part of the MSP430™ family of ultra-low-power MCUs. These MCUs consist of several devices, featuring different sets of peripherals targeted for various applications. The architecture, combined with five low-power modes, is optimized to achieve extended battery life in portable measurement applications. The Texas Instruments MSP430F261x / MSP430F241x series are MCU configurations with two built-in 16-bit timers, a fast 12-bit ADC, a comparator, two 12-bit DACs, four USCI modules, DMA, and up to 64 I/O pins. The MSP430F241x devices are identical to the MSP430F261x devices, with the exception that the DAC12 and the DMA modules are not implemented. The LQFP-64 package is also available as a non-magnetic package for medical imaging applications.
